Primaforce Peak O2 is an advanced supplement that increases physical capacity. Unlike pre-workout supplements, its activity is not short-term, but permanent, resulting from everyday supplementation and clearly visible after just a week of taking the preparation.

The supplement is based on 6 fungi used commonly in Ayurveda, that is ancient Indian medicine. They contain active substances belonging to the group of adaptogens, that is compounds which help the organism to adapt to environmental factors. They increase tolerance to stress factors, reduce mental stress, and are often used to reduce cortisol levels. This supplement contains extracts of the fungi whose ability to increase physical capacity has also been proven. Taking the supplement regularly accelerates regeneration, increases exercise capacity both in aerobic and anaerobic conditions, and delays the feeling of tiredness during workout. It is a perfect way to support sports performance, regardless of the discipline. The product contains:

Cordyceps – known in Traditional Chinese Medicine, sometimes called the “the miracle drug”, which stems from its extraordinarily wide range of effects. It was believed to help in the case of diseases of practically every system in the organism. Currently, based on recent scientific studies, it is used for strengthening the organism’s functions rather than as a drug. It can be found in many preparations increasing potency and sex drive because of its ability to stimulate them. In terms of physical capacity, the important aspect of cordyceps is the content of adenosine. It is one of the components of ATP, a universal energy transporter in the human organism. The fungus also has the ability to regulate the functions and increase the efficacy of the cardiovascular system by regulating heartbeat and dilating the lumen of blood vessels. It is beneficial for the regeneration and nutrition of muscles, which translates into increased exercise capacity.

The increase of energy mechanism efficacy can also benefit from the ability of cordyceps to increase insulin sensitivity in cells. That allows their better response to the hormone, so important for normal carbohydrate metabolism, which boosts the efficiency of the processes taking place on a cellular level. It also reduces the risk of adipose tissue deposition and the development of type 2 diabetes.

Reishi – in Ayurveda, it is mainly used as a drug for respiratory system and kidney diseases, as well as for stimulating regeneration when the organism is weakened. Reishi was recommended, for example, to women in the postpartum period as a way to regain their full strength after birth. The property has been confirmed by scientific tests, which is why reishi is used as a way to increase exercise capacity and support post-workout regeneration. The efficacy of the fungus in terms of strength restoration is so great that it is recommended as an aid in chronic fatigue syndrome treatment. Similarly to cordyceps, reishi is also able to increase insulin sensitivity in cells, which translates into the stimulation of carbohydrate metabolism.

Moreover, the fungus is of significant help to the immune system, as it increases the number of T lymphocytes and macrophages, that way boosting the potential of the immune response. It is recommended in cancer prevention as well.

King Trumpet MushroomPleurotus eryngii, a mushroom used commonly by athletes because of its ability to stimulate erythropoiesis. Supplementing it is connected with an increased number of red blood cells, which translates into greater exercise capacity. Erythrocytes are structures responsible for transporting oxygen to and removing carbon dioxide from working cells, so an increase in their number directly increases the ability of skeletal muscles to work more efficiently and for longer. After a workout session, it is connected with more efficient regenerative processes.

King Trumpet affects the health of the cardiovascular system by regulating the lipid profile as well. Moreover, it contains antioxidants, which help to reduce the level of free radicals, whose activity leads to cell apoptosis and consequently, accelerates the symptoms of aging.

Shiitake – mushrooms native to East Asia. They are a source of many vitamins and minerals, especially potassium and vitamin A. They are appreciated in traditional medicine mainly because of its fantastic effect on the health of the cardiovascular system. They reduce cholesterol levels and regulate blood pressure. When it comes to stimulating exercise capacity, the important aspect of shiitake mushrooms is the high content of vitamins of the B complex. They have a beneficial effect on energy metabolism, which helps the organism to use calories obtained from nutrients delivered with food more efficiently. Shiitake mushrooms also have a beneficial effect on adrenal functions, which affect the efficiency of energy functions in the organism by producing steroid hormones that regulate metabolism.

Lion’s mane – a mushroom also known as bearded tooth, satyr’s beard, etc.; it provides compounds of the erinacine group, able to stimulate the synthesis of the nerve growth factor. That way, it complements the content of the preparation with the ability to increase workout capacity through the stimulation of the nervous system. Clinical studies demonstrate that lion’s mane supplementation increases cognitive functions by facilitating fact association and remembering. Stimulating nervous system functions is also connected with increased nerve-muscle cooperation, which translates into an improvement of physical capacity. Lion’s mane supplementation is also effective in neurodegenerative disease treatment.

Lion’s mane exhibits the ability to regulate inflammation development in the organism as well. It helps to enhance regenerative processes and reduce too strong inflammations that limit the organism’s capacity.

Turkey tail – a mushroom used in the treatment of the flu and its derivatives, able to alleviate the symptoms of the disease. It is also popular in cancer treatment, as it reduces the intensity of side effects in patients subjected to chemotherapy. It stimulates regenerative processes in patients whose organisms are weakened by long-lasting therapy and disease. The effect is also used in sports supplementation, where turkey tail is used for accelerating post-workout regeneration. Supplementing the mushroom regularly also increases energy levels and has an antioxidant effect.

To sum up, Primaforce Peak O2 is a preparation that, despite being based solely on components of natural origin, exhibits powerful properties when it comes to promoting physical capacity. It makes it possible to train more intensively and more efficiently, at the same time reducing the time needed for regeneration. It is a versatile supplement whose advantages can be appreciated by every athlete, regardless of the discipline.

Calories are the conventional name of the unit expressing the energy value of food, the demand and energy expenditure in human body, which in fact is 1 kilocalorie (1 kcal). 1 kilocalorie is the amount of thermal energy required to heat 1 g of water and 1 degree Celsius. The SI unit of thermal energy is 1 joule (1J), equal to approximately 4,185 kcal.
The energy value is determined by the chemical composition of the food product, by means of the so-called. physiological equivalents. Most often Atwater equivalent is used: ratio for protein 4 kcal / g, for carbohydrates 4kcal / g, and for fat - 9kcal / g.
The energy value carried out with the so-called. "Caloric bomb" is equivalent to the physical energy, amounting to 4.1 kcal per 1 g carbohydrate to 5.65 kcal per 1 g protein, 9.45 kcal per 1 g of fat.
Nutritional value, determines the suitability of a food product for realizing life functions of human, the higher it is - the higher bioavailability and lower quantity for consumption for obtaining the effects.




Sugars - is the term used to refer to the crystal structure of the carbohydrate (sugar), characterized by a sweet taste. This group includes: sucrose (obtained from sugar cane and sugar beets and natural foods), fruit sugars (fructose) and glucose. Carbohydrate intake should not exceed 10% of the energy consumed during the day meals. Excess intake of sugars leading to diseases, including diabetes, atherosclerosis and obesity. Particular caution should be performed carbohydrate intake by athletes of sculpting disciplines and people on a diet. A greater need for carbohydrates, due being easily accessible sources of energy, may be in the periods before and after workouts and before and after the fight. Preparations available at



Reishi (Ganoderma lucidum), also known as Ling Zhi and “mushroom of immortality”, is a fungus used for more than 4000 years in traditional Chinese and Japanese medicine. Previous studies indicate a significant impact of this mushroom, especially on boosting immunity, reducing stress and preventing carcinogenesis processes.

The action of reishi is targeted on the modulation of the immune system. It has been shown that it has the ability to curb the activity of this system in the case of its excessive stimulation and increase it in the event of immunodeficiency. What is more, reishi has a positive impact on carbohydrate balance (may reduce blood glucose levels), optimises the lipid profile and promotes healthy neurological function (exerts a sedative effect and reduces mental strain).

Therapeutic effects of the fungus are produced by more than one main component. It is believed that a range of substances is responsible for its action, mainly polysaccharides, peptidoglycans and triterpenoids.

Reishi supplementation is recommended mainly as a general preventive measure to boost immunity, optimise carbohydrate metabolism, reduce chronic fatigue and increase vitality.

Our store offers a wide selection of preparations with high-quality reishi extracts, standardised to contain the most important active substances – polysaccharides and triterpenes.
